Mital, I really like the rim light on the edge of the wings. Good eye contact, and I like the full wingspread and fanned tail. Comp wise, I feel taking some off the top and moving him to the ULC will work better.
Kestrels are so awesome, but incredibly skittish here. I'm still waiting for one.
The bird is a bit small in the frame for me and the harsh angled light is hurting this image imo.
I would run NR on the bg and crop tighter if it'll hold up.
